[Qemu-discuss] PCI device memory access

Hi all,
I have created a new PCI device in Qemu 1.0.1 using i386-softmmu as
target system. Now, I am trying to make this PCI write to memory
location 0xd3f80 (which is in the pc.ram area).
Anyway, direct access with (*(unsigned char*) 0xd3f80) = value makes
Qemu crash returning a segmentation fault.

Does anyone have an idea how to solve this memory access problem? I'm
very grateful for any help or hint!

Thanks in advance,
Christoph Schneider
